Ferrochrome Lignosulfonate

Main Function

Ferrochrome lignosulfonate work as deflocculants and a fluid loss control agent for water based mud systems. It has excellent deflocculating properties at elevated temperatures and in the presence of Contaminants and Functions well in Both Salt water and Fresh water Systems effectively.Function is as following

Highly effective Deflocculants and rheology stabilizer
Functions well at elevated temperatures and in the presence of Contaminants
Excellent thinning and filtration control Properties
It also functions as a good emulsifier and provides Secondary Filtration Control
High Solubility and Mixes well in all types of Mud Systems functions in both Fresh water and Salt water Systems
Tolerant and continues to function well in High contamination Systems
Effective over wide Range of PH.
